Acetylcholine (ACh) has been detected in representatives of many taxonomic groups
throughout the plant kingdom. The site of its synthesis in plants is probably young
leaves. In some plant species choline acetyltransferase ...

In developing root hairs of Sinapis alba the effects of externally applied indole-3-acetic acid (IAA) and other auxins have been investigated with respect to membrane potential, membrane conductance, cytosolic Ca2 + and ...

The regulation of cytosolic Ca2+ has been investigated in growing root-hair cells of Sinapis alba L. with special emphasis on the role of the plasmamembrane Ca2+-ATPase. For this purpose, erythrosin B was used to inhibit ...

Photomorphogenesis of tomato is being studied with the aid of mutants which are either modified in their photore-
ceptor composition or in their signal transduction chain(s)
. Several mutants affecting the phytochrome ...

Calcium ions, calcium ionophores A23187 and ionomycin, as well as caffeine, stimulated the flowering of Pharbitis nil when applied just before and 2 h after starting a subinductive, 14-h long dark period. Effectiveness of ...

The effect of white (WL) and red (RL) light on organogenesis in vitro was studied using explants isolated
from seedlings of wild-type (WT) and two photo morphogenic mutants of tomato (Lycopersicon esculentum
Mill.) - ...

The aim of this study was to combine saline ecosystem structure and function by three
aspects of the gradient concept: spatial, temporal and functional. The saline meadow was investigated in the vicinity of soda factory ...

Biochemical and genetic studies have identified peptides that
play crucial roles in plant growth and development, including
defence mechanisms in response to wounding by pests, the
control of cell division and expansion, ...

Brassinosteroids represent a class of plant hormones with high-growth promoting activity. They are found at low levels in pollen, anthers, seeds, leaves, stems, roots, flowers, grain, and young vegetative tissues throughout ...

Using the radiometric method, the activity of acetylcholinesterase (AChE, E.C. 3.1.1.7) was studied in seedlings of wild type (WT) and of
phytochrome mutants of tomato (Lycopersicon esculentum Mill.). The activity of this ...

This study presents the results of research conducted at two early-medieval fortiﬁed settlements situated on the border of Wysoczyzna Chełmińska (Chełmińska Upland) and neighbouring areas. Phytosociological surveys were ...

The mechanisms of vegetation zonation were determined in order to provide an advice for restoration of natural saline habitats. Field experiments were conducted to examine the response of mature plants to different edaphic ...
